Folks-
I have not installed mine yet but this winter I did purchase a K&N universal air filter off Amazon:
Amazon Description: (in case the link below does not work)
K&N RA-0470 Universal Clamp-On Air Filter: Round Straight; 2.063 in (52 mm) Flange ID; 4 in (102 mm) Height; 5.875 in (149 mm) Base; 5.875 in (149 mm) Top

This past summer was our initial season with our T37 powered by the Universal 5432. We had a unusual amount of diesel/engine fumes in the cabin during and after operation... Upon further inspection, the engine crankcase vent had come unattached and was simply spewing fumes into the engine compartment. Not sure if this is my root cause for the diesel/engine fumes and smell, but I'm starting with attaching the vent line directly to this K&N air filter in attempt to eliminate the fumes. It has an optional inlet on the back for a vacuum line (shown in the 4th picture from the top on Amazon) and I intend to connect the vent line directly to this vacuum line on the filter.
Has anyone else had this problem and/or a solution?
Hope to provide an update in the next 60-90 days once the boat has been in the water for a month or so with some hours on the experimental solution.
